About the lecture

In this lecture, we think about the key data collection method in a natural experiment – observation, focusing in particular on: (i) distinguishing between naturalistic (present here) and controlled observation, as well as between overt, covert, non-participant, and participant observation; (ii) comparing naturalistic and controlled (often laboratory) observations, using Ainsworth’s ‘Strange Situation’ as an example of the latter and Mehl’s talkativeness study as an example of the former; (iii) distinguishing between overt and covert observation, highlighting the potential ethical concerns with covert observation and discussing ways of overcoming them, such as having participants provide retrospective consent; (iv) the benefits of participants being unaware that they are being observed; (v) distinguishing between participant and non-participant observation, highlighting that covert participant observation occurs very rarely in modern psychology, due to ethical restrictions.

Glossary:

Participant Observation – A research methodology where the researcher immerses themselves among the activities of the participant(s) and/or within the phenomenon that is being studied.
